“…This pathogen was found as part of the skin flora on humans and animals and has been suggested as a cause of abortion in cattle and humans [27]. Furthermore, it has been also associated with urinary tract infection [28], meningitis [29], orthopedic infections [27], and endocarditis [30]. On the other hand, K. pneumonia, inhibited by ethanol extract of H. verticillaris in the present study, a pathogen, can cause inflammation and hemorrhagic in human lungs.…”

In this study, phenolic compounds and antimicrobial properties of four medicinal plants from Nigeria was investigated. The antibacterial properties and minimum inhibition concentration of Microdesmis puberula, Hypoestis verticillaris, Icacina tricantha, and Enterolobium cyclocarpum against 21 different bacteria was carried out using the disc diffusion assay. These plant extract were subjected to phytochemical screening by reverse phase HPLC (high pressure liquid chromatography) coupled with diode array detection and GC-MS (gas chromatography-mass spectrum). H. verticillaris had the most significant activity and showed inhibitory activity against most of the Gram-positive bacteria. However, M. puberula was only effective against the growth of Staphylococcus aureus and Enterobacter sakkai with inhibition zone of 8 mm. Furthermore, both I. tricantha and E. cyclocarpum only had antimicrobial effect on S. warneri with the inhibition zone of 12 and 13 mm, respectively. The results showed that M. puberula mostly contained 0.46 mg100 g-1 dry sample quarcetin and H. verticillaris contained approximately 0.7 mg 100 g-1 dry sample mangiferin and quarcetin. Moreover, both I. tricantha and E. cyclocarpum contain mostly quarcetin and rutin. According to GC-MS results, M. puberula contained thymol and methyl cinnamic acid and H. verticillaris contained methyl cinnamic acid and gallic acid. These plant extracts can be considered to be used in the cosmetic and food industries or even as a safe alternative to synthetic antimicrobial drugs.

Categorisation of culturable bioaerosols in a fruit juice manufacturing facility

2021

Bioaerosols are defined as aerosols that comprise particles of biological origin or activity that may affect living organisms through infectivity, allergenicity, toxicity, or through pharmacological or other processes. Interest in bioaerosol exposure has increased over the last few decades. Exposure to bioaerosols may cause three major problems in the food industry, namely: (i) contamination of food (spoilage); (ii) allergic reactions in individual consumers; or (iii) infection by means of pathogenic microorganisms present in the aerosol. The aim of this study was to characterise the culturable fraction of bioaerosols in the production environment of a fruit juice manufacturing facility and categorise isolates as harmful, innocuous or potentially beneficial to the industry, personnel and environment. Active sampling was used to collect representative samples of five areas in the facility during peak and off-peak seasons. Areas included the entrance, preparation and mixing area, between production lines, bottle dispersion and filling stations. Microbes were isolated and identified using 16S, 26S or ITS amplicon sequencing. High microbial counts and species diversity were detected in the facility. 239 bacteria, 41 yeasts and 43 moulds were isolated from the air in the production environment. Isolates were categorised into three main groups, namely 27 innocuous, 26 useful and 39 harmful bioaerosols. Harmful bioaerosols belonging to the genera Staphylococcus, Pseudomonas, Penicillium and Candida were present. Although innocuous and useful bioaerosols do not negatively influence human health their presence act as an indicator that an ideal environment exists for possible harmful bioaerosols to emerge.

“…We describe the case of Staphylococcus warneri UTI in patient with liver cirrhosis resistant to beta-lactam antibiotics. Liver cirrhosis, irrespective of the cause, is known to cause immunocompromised state [5]. Cirrhosis impairs several aspects of immune response related to both innate and adaptive immunity [6,7].…”

Coagulase negative Staphylococci often grow in cultures and form one of the most abundant flora among skin microbiome. It is important and challenging to identify and treat clinically significant infections caused by these organisms. Prosthetic devices, catheters and conditions causing immunocompromised states are the risk factors for such infections. We describe a case of clinically significant and symptomatic urinary tract infection (UTI) in a 65-year-old man with liver cirrhosis caused by Staphylococcus warneri which forms <1% of Staphylococcal skin flora. He was treated successfully with fluoroquinolone antibiotic based on culture results. It is important to understand potential of this organism to cause serious infections which warrant culture-directed antibiotic therapy.
